In which of the following regions would exfoliation commonly occur?
Answer Details
Exfoliation is a type of weathering process in which curved plates of rock are stripped from rock surfaces due to release of pressure on the underlying rocks. This commonly occurs in regions with large diurnal range of temperature such as semi-arid regions. This is because, during the day, rocks expand due to heat and contract during the night due to cooling. The repeated expansion and contraction of rocks over time causes them to weaken, crack and eventually shed the outer layers of rocks. Hence, the answer is: Semi-arid regions with large diurnal range of temperature.
